    SBT?-510 is a high-performance, eco-friendly concrete admixture developed by Sobute New Materials Co. Ltd. SBT?-510 can shorten the cement induction process and promote early formation of hydration product, thus accelerating hydration and early-age strength development. With SBT?-510, early-age strength (<24h) can be significantly improved with no negative effects on later-age strength and durability. The production cycle can be also shortened, and energy cost can be saved. It is optimized for concrete requiring quick early-age strength development, e.g., prefabricated construction, tunnel segments and PHC.
